SPRINGLESS LOCK.

Application filed September 2, 1913.

To all whom it may concern:

Be it known that I, SAMUEL GARVIN, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a newand useful Springless Look, of which the following is a specification.

My invention relates to that class of locks, which are operated by coins introduced through a slot in the casing; and the objects of the invention are,'first, to provide a lock which can be operated by the door-knob and a coin dropped into the look, without the aid of a key; second, to provide such a lock, which can be operated by but one specific class of coins; third, to provide such a lock, wherein the coin will remain in such position that the lock can not be operated and other coins cannot be introduced until the door is closed and the lock released; fourth, to provide such a lock, wherein the mechanism will be operated without any springs or other delicate and breakable members; fifth, to provide such a lock, which will be proof from picking and sixth, to provide such a lock, which may be opened and closed by a pass key without in any manner affecting'the mechanism or exposing the coinchamber.

The purpose of the invention is to provide a means of collecting a small service fee, at public closets, lockers and other similar places.

These objects I attain by means of the mechanism illustrated in the accompanying drawings, in which Figure 1, is a view of the interior of the lock showing the bolt extended and a coin in place to operate the lock. Fig. 2, is a perspective view of the lock and keeper. Fig. 3, is a view of the interior of the lock showing the bolt withdrawn. Fig. l, is a view of the interior of the lock, showing the bolt extended and the coin-slot open. Fig. 5, is a perspective detail of the tumbler. Fig. 6, is a perspective view of the coin-guard.

Similar letters and numerals of reference refer to similar parts throughout the several views.

The letter A indicates a metallic casing, consisting of a back 7) and a cover 0. The back 5 is a flat metallic plate of elliptical outline and adapted to support the mechanism of the look as hereinafter more fully described.

The cover 0, consists of a metallic plate of Specification of Letters Patent.

outline similar to the back 6, and with a pendant flange d extending entirely around the outer edge thereof, said flange 03 being adapted to fit closely around the back 6, thereby inclosing the back and providing space between the back 6 and the face of the cover, for the reception of the lock mechanism and a chamber :12, for the reception of coins dropped therein. A slot 40 is cut through the upper portion of the cover 0, to admit the projecting dial of the indicator 6 and to provide for the admission of a coin, which is slipped through the cover immediately below the indicator.

The back 6 is slotted at the top to receive an indicator 2' and is provided, immediately below said indicator, with a raised coinguide j, which directs a coin dropped through a slot lO provided therefor, in the top 0 immediately below the indicator, to a point immediately over the bolt f. The coin-guide 1s concaved upon the upper face and the two edges 7 and 8 thereof, form bearings upon which the hereinafter described slotguard e rests and moves. A stud 6 projects upwardly from the coin-guide j and serves as a guide for the slot-guard e. The slot-guard e is a lever of a modified l-l form, as shown, and is provided at the upper end of the longer arm thereof, with a notch 7a, the edges whereof are beveled, from the bottom outwardly, for the purpose of engaging and rocking a pin 79, which projects from the shaft of the indicator 2'. The indicator 2' may be of any one of the well known types of indicators which operate by a ratchet movement. A curved bolt 7 is suspended upon a link-bar g, which is attached to the back 5 by means of a pivot-screw it, upon which the same is free to swing pivotally. The coin-guide j is rounded upon the lower edge to conform with the arc of a circle through which the curved bolt 7 swings and the said bolt is mounted properly to cause the upper edge thereof to swing around and adjacent to the raised and curved lower edge of the coin-guide. The bolt f is provided with the slot 1- in the lower portion thereof and is adapted to receive therein and'guide the coin-guard m, as hereinafter more fully described. A. slot Z is provided in the upper portion of the bolt 7', adapted to admit the knob-bar or tumbler l2, hereinafter described and to permit free swing of the bolt. The outer face of the bolt f is cut down to form the bearings 0 and p, for the coinguard m and to correspond exactly in height with the lower edge-of the coin-guide j. A

lug 9 projects outwardly from the lower and outer face of the bolt 7 atthe lower end of the slot Z, and is adapted to intercept and hold a coin-V,- between itself and the C0lIlguard m, when the bolt f is extended. A heavy cam-like weight 15, is mounted upon the extreme upper end of the bolt 7", adapted to throw the bolt normally extended and to actuate the bolt means of the dog 14, controlled by the knob-bar or tumbler 12. i A fork-likejcoin-guard m, is provided upon the reverse side thereof, with two pendent flanges n,which are adapted to fit against the walls of the slot 1, respectively, and to slide'against said walls, for the purpose of holding the coin-guard in proper place.

i The lower face of the coin-guard on slides back and forth upon the bearings 0 and 79 formed by the upper face of the bolt f.

The letter W indicates a tumbler which consists of a hollow shaft a, shouldered and finding bearings in the back .7) and the cover 0, respectively, atumbler-bar .w extending laterally from said shaft a and rounded upon its eXtremeouter end, to fit'into the cam-like orifice 2 provided in the coin-guard therefor; and a laterally projecting dog 6 extending from the shaft u, immediately below the tumbler-bar w, adapted to engage a socket t out. into the lower edge of the bolt f. A. knob K is mounted upon a square knob-bar 7c, which is mounted within the hollow shaft u, thereby causing the tumbler W to turn with said knob K. The knob K projects outwardly from the face of the cover a. The back his further, perforated,

immediately under the upper portion of the bolt; f, for the purpose of admittmg a knobbar 12, which enters from the rear of the back 6 and bears a camshaft 13, which stands within the slot Z cut into the bolt f.

The camshaft 13 is provided with a laterally projecting dog 14, adapted to bear against the cam-like weight 15 upon the up-' per end of the bolt 7, and a dog 16, prO ect- .7 ing laterally and adapted to engage the v notch 17 provided therefor upon'the under face of the longer arm of the slot-guard e. li he cam-shaft 13 is operated by a knob-bar 12, which. extends therefrom, through the V door upon which the lock is mounted and bears a knob upon its extreme outer end. I

A notch 20 is cut into the lower edge of the bolt 7, above the center thereof, adapted to receive thekey 21, which isintroduced through the cover a, and which is adapted to operate the bolt f without disturbing the other members of the lock mechanism.

The face'o-f thecover c is provided with an orifice 22, in the lower portion thereof and opening into the interior of the casing A, for the purpose of extracting coins dropped-thereinto, and said orifice is closed with an outwardly projecting stud 30, upon which the cover 0 rests and the cover 0, is

provided with' corresponding studs 31, which stand adjacent to, the corresponding studs 30; said studs 30 and 31 are grooved to receive a binding-wedge 32, whereby the cover 0 is firmly attached to the back b,

as shown by dotted lines, in Fig. 2. p

A. keeper 1) is mounted upon the doorjamb in proper position to engage the extended bolt 7".

To open a door equipped with my lock, a" nickel five cent coin is passed throughthe slot 10 and drops into the coin-guide j, from which itfalls into the space, upon the bolt 7, between the coin-guard and the stud.

q, where it lodges as shown in Fig. .1. The

outer knob K is then turned, thereby driving the coin-guard m and thecoin V backward and upward, by means of the tumblerbar w, and engaging the dog tin the notch or socket 6, whereby the bolt 7 is withdrawn from the keeper. Asthe coin V is pressed backward, it presses against the lower end of the longer arm of the slot-guard e and pushes the same upward until it registers V the indicator and covers the coin-slot 4:0.

The door is then opened, and closed from the inside, the jar of such closing together with gravitation, causing the bolt 7 to swing down into the keeper, without disturbing the slot-guard and incidentally driving the" coin-guard m downward and thereby re-' leasing the coin V, which falls into the coinchamber 00 below. The door is then opened from] the inner side, by turning the inner knob whereby the doglt is pressed against the cam-like weight 15 and raises the bolt 7. At the same time the dog 16 presses the slotv guard e downward into normal position and opens the slot 40; The door is then closed from the outside, and the jar thereof, causes the bolt f tofall into the keeper, thus bringing the look into normal position and with the coin-slot open. The action of the slotguard rocks the pin p and shaft of them- 'dicator and thereby registers each operation of the lock and resets the indicator fori further action. In case a porter wishes to open the door, he throws the bolt f bymeans of the pass key 21, thereby, in no Way disturb- 5 ing the other mechanism of the lock, and without possible access to the coin-chamber :0. To extract coin from the coin-chamber w, the cap 23 is removed by unlocking the lock 25 thereof, thereby opening the coin-chamber without. disturbing the mechanism of the lock.

The advantages claimed for my look over other locks used prior hereto for similar purposes consist, in the absence of all springs and other delicate and breakable devices, the avoidance of friction by reason of the gravity swinging of the bolt f, the automatic registration of the indicator and guarding of the coin-slot while the closet is in use, the possible operation of the bolt and the removal of coin, without disturbing the other members of the lock.

Having described my lock, its peculiar structure and operation, what I claim as new and desire to secure by Letters Patent, is

The combination with a lock casing and a coin guide open at its ends, of an arcuate bolt slidably mounted within the casing and having a coin receiving space normally registering with the outlet end of the guide, said bolt being weighted and normally projected to active position, there being a recess in the bolt for the reception of a bolt retracting key, a coin guard pivotally mounted in the casing above and beyond the bolt and slidably engaging the bolt, means carried by the bolt and cooperating with the coin guard for supporting a deposited coin within the recess in the bolt, manually operated means for shifting the coin guard relative to the bolt, thereby to engage a deposited coin in the face of the bolt and retract the bolt from normal position, a guard extending across the coin chute and slidably mounted therein, said guard being normally held by gravity in position below the inlet end of the coin chute, and means depending from said guard for engagement by the deposited cointo elevate the guard and close the inlet end of the coin chute when the bolt is retracted, and a second manually operated means for retracting the bolt, said last named means being extended from one side of the casing and the coin guard operating means being extended from the other side of the casing.
